NNLO vertex corrections in charmless hadronic B decays: Imaginary part
We compute the imaginary part of the 2-loop vertex corrections in the QCD factorization framework for hadronic two-body decays as B → π π. This completes the NNLO calculation of the imaginary part of the topological tree amplitudes and represents an important step towards an NNLO prediction of direc...
